Description
Technical field
The present invention relates to the fall webworm lure composition comprising fall webworm sex pheromone and synergist thereof, and this lure composition control and/or monitoring fall webworm in application and containing this lure composition lure core.
Background technology
Fall webworm (Hyphantria cunea Drury) endanger serious worldwide invasion insect, and originate in North America, within 1979, import China northeast into, nineteen ninety is classified as one of Chinese seven fully stocked wood damage by disease and insect by the Ministry of Forestry.Afforestation department bulletin fall webworm epidemic-stricken area comprises Beijing (9th district), Tianjin (12 districts/county), Hebei province (37 districts/county), Liaoning Province (41 districts/county), Shandong Province (25 districts/county) and Shaanxi Province (1st district), totally 125th district (county).Fall webworm have that feeding habits are assorted, breeding amount large, strong adaptability, the harm seriously and very easily Biological characteristics such as propagation, spread in above-mentioned regional wildness at present, the ecotope of heavy damage locality, affects economic development, and the harm controlling this insect seems very necessary.Within 1999, China starts Jing-jin-ji region fall webworm engineering control project, and the General Office of the State Council in 2006 issues the documents and require to administer fall webworm energetically March.
Usability pheromones monitoring means can to the carrying out of fall webworm in good time, accurate forecast, being conducive to adopts an effective measure in time is prevented and treated; Usability pheromones Insect pest suppression and a large amount of baiting technique can control the increase of fall webworm quantity, avoid again the pollution to environment.
Current use be that the import of raw material lures core to have high, the not easily universal shortcoming of cost with sex pheromone; such as the fall webworm sex pheromone of Beijing's Market Economy station application import lures core to monitor the generation of fall webworm in Beijing and its peripheral areas; it is active that this lures core to have certain trapping; but expensive, be difficult to large-scale promotion and use.4 components self-controls of domestic use lure core, relative inexpensiveness, and trap effect is also better, but due to continuation low, cause replacement cost and improve.
Therefore, need to provide a kind of and lure core containing fall webworm sex pheromone and synergist composition thereof, high to alleviate cost, difficult universal problem, simultaneously for the monitoring technology of fall webworm provides diversified selection.
Summary of the invention
The object of the invention is to overcome high, the universal difficult defect of fall webworm sex pheromone cost in prior art, the fall webworm lure composition comprising fall webworm sex pheromone and synergist thereof is provided, active with the consumption, the raising trapping that reduce sex pheromone, thus reduce costs.The present invention also aims to provide the application of described lure composition in control and monitoring fall webworm and lure core containing this lure composition.

The hexane solution of multicomponent synergist is made according to the composition in table 2, solution concentration is respectively 5 mg/ml, 10 mg/ml and 20 mg/ml, drip 200 microlitres respectively on the partition of the rubber stopper cleaned with n-hexane, dripped at twice by 200 microlitre carrene after n-hexane volatilization, after carrene volatilization, namely obtained synergist lures core.Lured by the multi-component synergist made core to load in aluminium foil to seal, preserve at-20 DEG C.
When carrying out trapping experiments in field, lure core to be fixed on Unitrap type or triangle trapper epimere synergist with thin wire, trapper is suspended on the branch of poplar of 3 ~ 5 meters high, coordinate fall webworm sex pheromone to lure core jointly to use simultaneously.The object of reference of this serial comparative trial is that import fall webworm sex pheromone lures core (Chu Guang Xing Productivity Co., Ltd., NITOLURE board, Japan produce) or self-control fall webworm sex pheromone lure core.Trapper spacing is about 100 meters, and trapper is changed position by every day, and it also removes by fall webworm quantity that record is traped in time.Result of the test is in table 1.
Described self-control fall webworm sex pheromone lures the preparation method of core as follows:
1. by following four kinds of compounds:
(Z9, Z12)-ten eight carbon two olefine aldehydr; (Z9, Z12, Z15)-ten eight carbon triolefin; (Z3, Z6, S9, R10)-9,10-epoxies-3,6-21 carbon diene and (Z3, Z6, S9,10R)-9,10-epoxy-1,3,6-21 carbon triolefin fully mixes according to constant weight ratio, and common part by weight is 0.5 ~ 3: 15 ~ 40: 50 ~ 65: 5 ~ 7, most preferably be 2: 33.6: 58.4: 6, use this most preferred part by weight in the present embodiment.
2. mixture step 1 obtained is dissolved in n-hexane according to a certain percentage, and the n-hexane pheromones solution concentration of usually configuration is about 500-1500ug/ml, and what use in the present embodiment is 500,1000 and 1500ug/ml.
3. the solution that step 2 obtains is about 200ul to be added drop-wise to blank rubber and to lure on core (The WestCompany, Phoenixville, PA), the dosage of the sex pheromone that the self-control sex pheromone lure core obtained contains is 100,200, and 300 μ g/ lure core.
